If they could make them small / sensitive enough to make them subdermal, without the risky brainsurgery, that would be an absolute gamechanger and would increase acceptance by a lot. if the process would be like getting a few piercings under local anesthesia, it would make servicing the hardware much less of a life and death decision, and i wouldn’t mind getting something like that - especially if it’s on the hackability scale of a steam deck lol
